To all whom it may concern:

Be it'known that I, ALBERTIS C. TAYLOR, a citizen of the United Statesof America, re'- siding at Warren, in the countyof Trumbull and State ofOhio, have invented certain new and useful Improvements in ElectricWelding-Machines, of which the following is a specification.

' The primary object of this invention is to enable the electrodes of anelectric welding machine to be readily and easily adjusted according tothe nature of the work or the shape of the articleto be welded.

In the'accompanying drawings, Figure-1 shows the upper portion of aspot-welding machine provided with my improvements. Fig. 2 is anenlarged side elevation ofthe lower electrode and its support. Fig. 3 isa plan view of Fig. 2. Fig. 4 shows in -eleyation and section 4one ofthe electrodes.' Fig. 5 is a diagrammatic view showing electrodes asemployed for welding a rectangular box.

Referring to the drawings, 1 designates a portion of an electric weldingmachine from which extend horizontally disposedv horns 2 and 3. The horn2 carries a plunger 4, which may be of known construction, and on thelower end of this plunger is a support '5 for the upper electrode 6. Tothe lower horn 3 is secured a support 7 for thev lower electrode 8.

Each of the supports 5 and to its outer end a radially-movable electrodeholder 9. These holders 'are shown inform'v of arms swiveled to theirrespective supports, so that by a rocking motion the electrodes may bedifferently positioned in respect to their supports.-v Preferably, each'holder is rounded at its inner end to fit ina socket formed in the endof its respective support, such socket being slightly greater thansemi-circular, and the side members of the socket are capable. of beingdrawn toward each other to firmly bind the electrode holders in thedifferent posltions they may be caused to' occupy. For this purposeIthe,

` vheads to accommodate the dies'or electrodes.

7 has secured While these dies or electrodes are preferabl y separable.lfrom their holders, yet lif desired,` they may be integral partsthereof.'- j Y I have shown ,the electrodes as having 'rel duced taperedends whereon are fitted re- 60 movable caps 14, and I have also shownthe electrodes as having tubes 15 for providing a circulation of waterwhereby the caps may be cooled, but these features constitutethe f o'rpatent, vSerial No. 668,418,iled' December 29, 1911, and hence furthervreferencev thereto is unnecessary. .The ,advantages of my presentinvention will be readily appreciated by those skilled in the art.Itwill be seen that by means'.

tioned by radially moving the arms constituting the electrode'holders,which latter rock in their respective supports. Hence it is unnecessaryto' provide diil'erent sets of electrodes or difere-ntsets of holderswhen the articles being welded have to be variously positioned relativeto ,the electrodes. This is especially true with boxes which re# 'quireto bewelded at different sides or corners. The adjustment of theelectrode holders into different positions` may be readily effected byloosening the bolts 12.'

It will be understoodthat my invention is not confined. to lthespecificconstruction or arrangement herein described, and that changes may bemade without departing from the invention as defined by the claims.

' vI claim as my invention:

` 1. In a welding machine, electrodes radially movable in the ends ofsupporting arms therefor.

2. In a welding machine, electrodes, supportstherefon saideleetrodesbeing radially movable relatively to said supports, and means forholding said electrodes in various positions. 3. Ina spot-weldingmachine, vswiveled lectrodes rocking in supporting arms thereor. l

4. In a spot-welding machine, electrodes, holders for the electrodes,supports therefor, said holders being vswiveled to said supports, andmeans'for retaining the holders in various positions. y

5. In'an electric welding apparatus, a die l or electrode carrying head,means carrying subject matter of a divisional applicationl 65 thereofthe electrodes may b e readily posi-y j such head for swivel movements,and a die or electrode carried by said head at one side of 4its turningaxis."

6.'In an electric Welding'machinaa die or electrode, and an arm carryingsaid die or electrode and attached to the machine for oscillatoryadjusting movements relative thereto. i

' 7. In an electric Welding machine, a plunger, an arm attached to theplunger for pivotal movements relative thereto, means for seeuring thearm ,in adjusted positions relative to the plunger, and a die o relectrode carried by said arm.

immessa 8. In an electric Welding: machine, a plunger, an arm att-achedthereto for oscil latory adj ustingmovements, a pin-likemembercoperating With'said plunger and arm to retain the same in adjustedrelation, and a die'or electrode carried by said'arm for swingingmovements therewith.

In testimony whereof I affixmy signature in presence of two Witnesses.

ALBERTIS C. TAYLOR.
